Technical Field

[0001] This utility model belongs to the field of automotive seats, and more specifically, it relates to an integrated adjustable headrest for a car seat. Background Technology

[0002] With the development of the automotive industry, drivers and passengers have increasingly higher requirements for comfort. Traditional headrests have limited adjustment functions, usually only adjustable up and down, with a few adjustable forward and backward. They cannot meet the comfort needs of users in different scenarios, especially when the seat is reclined at a large angle, making it difficult to provide effective support for the head.

[0003] Chinese Patent No. CN218702879U discloses an adjustable headrest and a child safety seat, comprising a first side pillow, a second side pillow, a middle pillow, a sliding member, and at least one inclined guide member connected in sequence. The middle pillow is connected between the first and second side pillows. The sliding member is disposed within the inner cavity of the middle pillow, and the inclined guide member is disposed within the inner cavity of the first and / or second side pillows, with the sliding member and the inclined guide member slidingly engaged. When the width of the headrest needs to be adjusted, the sliding member within the middle pillow can be moved by traction, adjusting the distance between the first and second side pillows, thereby achieving headrest size adjustment.

[0004] During later use, the device still has the following problems: the headrest cannot adjust the angle of the side pillows, it can only retract towards the middle, which is not a good experience in actual use. Adjusting too much can easily pinch the head, while adjusting too little does not provide enough support for the head. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 1 and Figure 2 As shown, an integrated adjustable headrest for a seat includes an integrated seat 1, with a headrest 2 slidably mounted on the top of the integrated seat 1. Side pillows 3 are provided on both sides of the headrest 2. By attaching the back of the side pillow 3 and pressing the pressure plate 801, the tilt angle of the side pillow 3 can be adjusted, improving the comfort of head support provided by the headrest 2 and meeting the needs of different users. The headrest 2 has a main frame 4 inside, such as... Figure 3 and Figure 4 As shown, a mounting rod 401 is fixedly connected to the bottom of the main frame 4. The mounting rod 401 is slidably connected to the integrated seat 1. When installing the headrest 2, the mounting rod 401 is simply inserted into the mounting hole of the integrated seat 1.

[0016] The main frame 4 has two fixed rotating grooves 402 on its rear sides, with a locking rotating frame 6 rotatably connected within each groove 402. The main frame 4 also has two fixed rotating grooves 403 on its front sides, with a side frame 5 rotatably connected within each groove 403. The side frame 5 cooperates with the side pillow 3. The main frame 4 supports and fixes the middle of the headrest 2, while the side frame 5 supports the side pillow 3. Adjusting the tilt angle of the side frame 5 changes the angle of the side pillow 3, thus adjusting the support angle of the side pillow 3 on the head. A slot 501 is fixedly provided on the side frame 5 to prevent interference between the side frame 5 and the adjusting support rod 7. A rotating hole 502 is fixedly provided on the slot 501, with an adjusting support rod 7 rotatably connected within each hole. A driving pressure plate 8 slides on the adjusting support rod 7.

[0017] By setting up a driving pressure plate 8, an adjusting support rod 7, and a locking rotating frame 6, the adjusting support rod 7 cooperates with the locking rotating frame 6 in the normal state, and the locking tooth 603A is engaged in the half tooth groove 702A, thus fixing the relative position of the adjusting support rod 7 and the locking rotating frame 6. At this time, the side frame 5 is locked, and the side pillow 3 supports the head. When the driving pressure plate 8 presses the adjusting support rod 7, the adjusting support rod 7 rotates, and the locking tooth 603A disengages from the half tooth groove 702A. The adjusting support rod 7 and the locking rotating frame 6 can slide freely for adjustment. At this time, the side frame 5 can rotate, causing the head tilt angle of the side pillow 3 to change.

[0018] The locking rotating frame 6 has a sliding cavity 601 inside. A sliding hole 601A is fixedly formed at the front of the sliding cavity 601, and the sliding hole 601A is slidably connected to the rotating rod 702. Two sets of limiting sliders 603 are slidably connected to the inner wall of the sliding cavity 601. Each limiting slider 603 has a locking tooth 603A fixedly provided. A compression spring 602 is fixedly connected to the other end of each limiting slider 603, and the other end of the compression spring 602 is fixedly connected to the inner wall of the sliding cavity 601. When the half-tooth groove 702A rotates to a vertical position, the limiting slider 603, pushed by the compression spring 602, engages with the half-tooth groove 702A, thus axially locking the rotating rod 702. When the half-tooth groove 702A rotates to a horizontal position, the limiting slider 603 disengages from the half-tooth groove 702A, and the limiting slider 603 loses its locking effect on the rotating rod 702.

[0019] like Figure 5 As shown, the adjusting support rod 7 includes a rotating base 701 and a rotating rod 702. One end of the rotating base 701 is rotatably connected to the rotating hole 502, and the other end of the rotating base 701 is fixedly provided with an opening 701A. The front part of the rotating rod 702 is fixedly connected with a rotating pin 702B, which is rotatably connected to the opening 701A. A guide groove 702C is fixedly provided on the middle side wall of the rotating rod 702, and a semi-tooth groove 702A is fixedly provided on the rear side wall of the rotating rod 702.

[0020] like Figure 6 As shown, the semi-tooth groove 702A cooperates with the locking tooth 603A. After the locking tooth 603A is inserted into the semi-tooth groove 702A, the adjusting support rod 7 and the locking rotating frame 6 are axially fixed.

[0021] The driving pressure plate 8 includes two sets of pressure plates 801. A sliding hole 801B is fixedly opened on the pressure plate 801. The sliding hole 801B is slidably connected to the rotating rod 702. A limiting protrusion 801A is fixedly provided on the inner wall of the sliding hole 801B. The limiting protrusion 801A is slidably engaged with the guide groove 702C. A compression spring 802 is fixedly connected to the inner side of the two sets of pressure plates 801. Under the push of the second compression spring 802, the two sets of pressure plates 801 maintain a separated posture. At this time, the limiting protrusions 801A move to the outside of the guide groove 702C. At this time, the half tooth groove 702A on the rotating rod 702 is in a vertical posture, and the locking tooth 603A on the limiting slider 603 can be engaged in it. When the two sets of pressure plates 801 are squeezed and move towards each other, the limiting protrusions 801A move to the inside of the guide groove 702C, and the rotating rod 702 rotates 90 degrees. At this time, the half tooth groove 702A on the rotating rod 702 is in a horizontal posture, and the half tooth groove 702A disengages from the locking tooth 603A.

[0022] Adjustment process: 1. Hold the back of the side pillow 3 with your hand, and the two sets of pressure plates 801 will be squeezed and move towards the middle against the pushing force of the second pressure spring 802; 2. The movement of the pressure plate 801 on the rotating rod 702 causes the rotating rod 702 to rotate 90 degrees, and the locking tooth 603A moves out of the half tooth groove 702A, only contacting one side of the smooth outer wall of the rotating rod 702, which facilitates relative sliding. 3. When the side pillow 3 is turned, the rotating rod 702 slides relative to the limiting slider 603, and the inclination angle of the side frame 5 changes. 4. After adjusting to the appropriate position, the two pressure plates 801 move away from each other under the push of the second pressure spring 802, causing the rotating rod 702 to rotate 90 degrees in the opposite direction. The half tooth groove 702A is aligned with the locking tooth 603A, and the two mesh again, locking the tilt angle of the side pillow 3.

[0023] This invention features a side pillow 3. By holding the back of the side pillow 3 and pressing the pressure plate 801, the tilt angle of the side pillow 3 can be adjusted, improving the comfort of the headrest 2 in supporting the head and meeting the needs of different people. The invention also includes a driving pressure plate 8, an adjusting support rod 7, and a locking rotating frame 6. In its normal state, the adjusting support rod 7 engages with the locking rotating frame 6, with the locking teeth 603A engaging in the semi-tooth groove 702A, fixing the relative position of the adjusting support rod 7 and the locking rotating frame 6. At this time, the side frame 5 is locked, and the side pillow 3 supports the head. When the driving pressure plate 8 presses the adjusting support rod 7, the adjusting support rod 7 rotates, disengaging the locking teeth 603A from the semi-tooth groove 702A. The adjusting support rod 7 and the locking rotating frame 6 can then slide freely for adjustment. This allows the side frame 5 to rotate, changing the head tilt angle of the side pillow 3.
